The carbothermic reduction process from the purified silica requires the granulation of raw materials Mixed silica and carbon granules were elaborated using several binders through a wet granulation process.
In order to improve this yield, an understanding of the behavior of each binder during the reduction process is required.
The effect of sodium (Na) in the binder on the carbothermic reduction will be discussed
